Hello all,
I've been trying to play some 4K videos (Bitrate around: 50 Mbps) in Kodi (HW: Sony Android TV X750D) but most of the time it starts stuttering and after that with no audio anymore. In general, the video doesn't play smooth.
So far, I tried the changes below in Kodi and Tv, but no success yet.
1 - TV Factory Reset
2 - Changed cache in many different ways (buffermode, memorysize and readfactor)
3 - In Video processing, disabled H/W acceleration in the following ways:
- Mediacodec and Mediacodec (surface) -> Video plays really slow (impossible to watch)
- Mediacodec (surface) -> Video plays really slow (impossible to watch)
- Mediacodec -> Video plays smooth but it start stuttering at some moments and get out of audio
Network setup I tried:
1 - Video source device and Tv in ethernet cable 1 Gbps (Even though TV has only 100Mbps ethernet port)
2 - Video source in ethernet cable and TV connected in the network with a 802.11ac (1900)
Conclusion: In both setup, the video source device is sending/receive 70Mbps in average when playing the videos.
I enabled Kodi's log and see that in average (during the video playblack) it's been using 400MB RAM and 115% (Kodi CPU).
Logs:
MemoryCacheEnabled: https://ufile.io/4hmvm
DiskCacheEnabled: https://ufile.io/2uy8g
Factory Config: https://ufile.io/bnbsf
PS: SOrry for not using pastbin but logs are bigger than 'free' option can handle.
TV Specs:
Model: Sony 65X750D (https://www.rtings.com/tv/reviews/sony/x750d)
Specs: 2GB RAM, 8GB Disk and 4 CPUs.
Example of Video Tested
How can I know if the hardware (TV) is being the bottleneck and has resources (CPU/MEM) enough to play those kind of videos?
Sincerely,
